The apples block does demonstrate the flow control even when a user with what

there is no sendPageAndWait functionality in the Apples example
CalculationApple.java. It only uses sendPage function.
sendPage is used normally for terminating the flow. ie., user should not be able to change the values of the shopping cart after the submit button is pressed. But the javascript does the same through k.invalidate(),
but in java it is not the same case.
There is no sendPageAndWait in Apples because Apples flow controller is
stateless. If you want to build stateful applications you have to manage
state yourself and store the information in session for example.
Check out the hanoi tower example.
